Emergency-department started mobile phone program to improve high blood pressure care

Reach Out 2: Randomized Clinical Trial of Emergency Department-Initiated Hypertension Mobile Health Intervention Connecting Multiple HealthSystems

NIH-funded research Northwestern University · NIH-11238927

It tests whether a phone-based program begun during an emergency department visit can help Black and low-income adults lower and manage high blood pressure.

What this research studies

If you have high blood pressure and visit a participating emergency department, you could be enrolled and offered a mobile health program that sends messages, medication reminders, and helps arrange follow-up care. Participants are randomly assigned to receive the phone-based intervention or usual care, and their blood pressure and care access are tracked over time. The program is designed to connect patients across multiple health systems, including safety-net hospitals, to improve medication use and clinic follow-up. The team will compare blood pressure changes and care engagement between groups to see whether the mobile approach helps.

Who could benefit from this research

Good fit: Ideal candidates are adults with high blood pressure who visit a participating safety-net emergency department, especially Black or low-income patients who use or can use a mobile phone.

Not a fit: People without hypertension, those who cannot or will not use a mobile phone, or those already well controlled on blood pressure treatment are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the program could help people lower their blood pressure and make it easier to get medicines and follow-up care after an ED visit.

How similar studies have performed: A prior Reach Out 1 effort with about 500 mostly Black participants showed a large average drop in systolic blood pressure but lacked a control group, so results were promising but not definitive.
